For a detergent raw-material buyer, the useful 2026 question is which supplier records should be organised now—not whether a generic “new-regulation certificate” can be attached to a surfactant quotation. Define the finished use and the buyer’s role before deciding which evidence is missing. Keep raw-material identity and finished-product assessment separate.
The current change and its scope
Regulation (EU) 2026/405 entered into force in March 2026. General application is 23 September 2029, with specified exceptions. Its surfactant and detergent framework distinguishes actors and documentation duties; the entry-into-force date must not be presented as the immediate start of every requirement.

Build the documentation chain around the offered grade
Give each qualified material a traceable grade identity. Link the quotation, sample, TDS/SDS and batch COA to that identity, and identify the contact who can provide composition or other relevant evidence. A surfactant family name is insufficient when two offered grades have different impurity controls or specification bases. Request the actual information available rather than assuming a label such as “environmentally friendly” proves an assessment.
Plan changes with the finished formulation owner
Before accepting an alternative supplier or grade, ask the responsible formulation team which changes need review. Separate material quality checks from finished-detergent obligations. A purchasing switch should record what changed, which documents were updated and which sample tests were agreed. If evidence is unavailable, record the gap and owner rather than declaring the finished product compliant.
| Buyer check | Question to resolve | Evidence to request |
|---|---|---|
| Identity | Exact offered SLES grade and source | Quotation/sample/document alignment |
| Specification | Active matter and impurity test basis | Grade-specific TDS and lot COA |
| Environmental evidence | Available test/document scope | Method, material and assessment scope |
| Change control | Supplier or grade substitution | Updated documentation and agreed sample checks |
Connect the assessment to the actual enquiry
Use the SLES/AES product page to request the actual grade and its documents. Standard and low-impurity catalogue options are not interchangeable regulatory evidence. Confirm the proposed specification and its methods; this article does not certify a MOS grade or a finished detergent.
Prepare a specific RFQ
Send an RFQ stating the detergent application, target market, SLES grade and active-matter/test basis, formulation constraints, quantity, annual demand, packaging and destination. Request TDS/SDS/COA and specify the composition or biodegradability information needed for your assessment. Confirm which documents are available and what sample validation remains.
Buyer questions
Are all new detergent duties mandatory in 2026?
No. General application is September 2029 with specific exceptions; verify the relevant provision and actor.
Does the name SLES establish biodegradability evidence?
No. Ask for the relevant grade/material test or documentary evidence and its scope.
Can a raw-material COA certify the finished detergent?
No. A quality COA and a finished-product regulatory assessment answer different questions.
What should a SLES supplier change record contain?
Record grade identity, specification/test basis, updated documents, formulation-owner approval and agreed sample checks.
